I'd like to instruct puppet to apply the configuration (via cibadmin) to a shadow config, but I can't find any sure way to do this. The issue is that running "crm_shadow --create ..." starts a subshell, but there's no easy way I can tell puppet to run a command, then run another command in the subshell it creates.

I've never tried this specific use case, so bear with me while I go
out on a limb, but the crm shell is fully scriptable. Thus you
*should* be able to generate a full-blown crm script, with "cib foo"
commands and whathaveyou, in a temporary file, and then just do "crm <
/path/to/temp/file". Does that work for you?

Florian
